I have some iOS 7 questions and I apologize if they've been answered already - I figure things have changed with every beta and was curious about the latest info regarding AirDrop. 1. Is it true that AirDrop requires you to have the other person's Apple ID email address for AirDrop to work? Or is it like iMessage where it uses your telephone number as the ID? 2. Also, what would happen if my friend AirDrops me a Pages document, but I don't have the Pages app? Thanks in advance!
